Implementation: Web Server, create a new web site project.
Explanation, to transfer large files using WCF service http, we can use the following types of bindings: wsHttpBinding basicHttpBinding, in wsHttpBinding, we can set the transfermode attribute as Buffered, but there is a disadvantage in using this approach for large files, because it needs.
Xml fileStream new thenticationKey, aoe 3 vista patch fileStream byte buffer new byte2048; int bytesRead ad(buffer, 0, 2048 while (bytesRead gt; 0) fileStream.
This is a workaround to fix a problem I was having with streams being left open.Alternatively, in VS 2008 SP1, you can use the "WCF Service Configuration Editor" - see it in "Tools WCF Service Configuration Editor".It seems like a little bit of a hack, but I scratched my head trying to find a solution to this, and this is the best thing I could come up with.I recently had to write some code to perform an upload to a WCF service, and there was a chance that the files could be a touch on the large side so streaming seemed like the best option.Onfig file to accept large file?xml version"1.0" encoding"utf-8"?Length while (bytesRead 0) / Verify that the client is connected.You need to start by defining some message contracts for your upload / download.Flush ose tFileName(leName OK so now we have a file upload method, download method, and the required contracts we need."Successful MoveToFailedFolder(e else if (File.Null) new Logger.Create(me, w, sponseStatus, ssage else new Logger.Create(me, w, "Error ssage Finally you need to steup the config file of the receiver?xml version"1.0" encoding"utf-8"?
Use an nfig like this (when you use "Add Service Reference" from Visual Studio, VS will typically create this for you automatically - and you just need to tweak it to your needs configuration rviceModel bindings basicHttpBinding binding name"UserNameSecurity" security mode"Message" message /security /binding /basicHttpBinding.

This Article trying solve this issue using WCF and TCP and streaming, in this artical will build the client and server at the end we will be able to send 75 MB file in less then 12 seconds.
